Abstract

Platinum catalysts based on porous aromatic frameworks (PAF-30 and PAF-30–SO3H) have been synthesized. Properties of the obtained catalysts have been assessed via hydrogenation of guaiacol, veratrole, and pyrocatechol at 250°С and hydrogen pressure 3.0 MPa in isopropanol medium. It has been shown that the presence of acidic sites in the catalyst significantly increases the yield of deoxygenation products. The effect of the substrate structure on the rate of its hydrodeoxygenation and the mechanism of the occurring processes have been studied.

多孔芳烃骨架结构中磺酸盐基团对铂催化剂对生物燃料组分加氢脱氧活性的影响

摘要

已经合成了基于多孔芳族骨架(PAF-30 和 PAF-30-SO 3 H)的铂催化剂。所得催化剂的性能已通过愈创木酚、藜芦醇和邻苯二酚在 250°С 和 3.0 MPa 氢气压力下在异丙醇介质中的氢化进行评估。已经表明,催化剂中酸性位点的存在显着增加了脱氧产物的产率。已经研究了底物结构对其加氢脱氧速率的影响以及发生过程的机制。
